I noticed that when there was less water and more pressure, the rocket had a better flight. Also, when the center of gravity was higher, the rocket had a better flight. I found the elliptical nose to work better than the conical nose. I messed around with the fin designs for a while but was never able to determine which fin design gave the best flight.
